See the second post of the thread for flashing instructions. If you're thinking about using ODIN to do it, you should probably read that post.
Dear Chainfire, I met below problem when using CF ROOT KJ1 /KJ 4 ( both Firmware):
-After backup, using CWM recovery I can not restore date ( MD5 mismatch)
-Mobile Signal interupt sometime ( Can not find mobile provoder, then again, ), This happen not all the time, but I faced 3 times, one with KJ4, 1 with KJ1 and 1 with KK1 ( not your kernel), then back to KJ1, thing is normal now. But I am not sure if it will happen again some time.
When can not find mobile system, I checked in flight Mode row and found that, it work automatically, some time auto checked and then unchecked, then checked again,
Surprisingly, but can not happy with this status, Can you check and find the reason, may be cf root hv some mistake, because when i use stock, nothing happen. But without rooting, as you know we can do nothing with backup with data.
to summarise: CWM can not restore data as usual, and flight Mode automatical checked & unchecked some time. Not all the time, but it happen 3 time for me.
many tks in advance!
